Semtech 的 LoRa Edge™ 室内和室外地理定位平台走向全球

Location is a vital component of the Internet of Things (IoT), encompassing the ability of things to sense and communicate their geographic position. Location data helps organize, track and account for the billions of Internet-connected devices based on sensors and other location-centric elements within them. The ability to capture location data forms the basis of location-based services and starts with the physical radio frequency (RF) technologies that interact with the world around them.

Several technologies, such as GPS, LoRa® and others, can provide outdoor location information. However, these existing technologies are not optimized for IoT asset tracking use cases due to their increased power requirements which require access to frequent charging as well as inability to work indoors. Reducing power consumption on devices fundamentally requires a reduction of compute on device, with IoT this can be accomplished by partitioning the workload between the device and harnessing the power of the Cloud. For precise indoor location, where GPS has no tangible reach, and to enable continuous location detection or tracking, indoor positioning systems (IPS) technologies such as Wi-Fi come into play.

Smarter, More Efficient Asset Management

借助云的力量，Semtech 的 LoRa Edge™ 能够独一无二地结合来自 LoRa、全球导航卫星系统 (GNSS) 和 Wi-Fi 无源扫描的位置信息，在单一节能解决方案中提供连续的室内和室外定位服务。自 2020 年推出产品以来 ，北美和欧洲的客户和解决方案供应商一直在利用其基于云的分布式地理定位求解器，通过广泛采用的 LoRaWAN® 网络传输设备位置数据。

如今，客户可以利用这个低成本的地理定位平台，在全球范围内获得最佳的电池寿命和端到端的强大安全性。具体而言，我们通过增加新的 ISM 频段，将 LoRa Edge 的使用范围扩大到了 915MHz (US915) 和 868MHz (EU868)）频率之外。以下频段信道已得到 LoRa Alliance® LoRaWAN 地区参数规范的支持，并且最近也已获得了所需的监管审批：

• AS923 (with four sub-regions for Japan, Indonesia and Australia/New Zealand)

• IN865 - India

• KR920 - Korea

• RU868 - Russia

• AU915 - Australia

Advanced Geolocation Portfolio of Solutions

Semtech 的 LoRa Edge 是一个多功能的硬件、软件和云服务平台。它由三个部分组成：LoRa Edge LR1110 收发器芯片、LoRa Basics™ Modem-E 或 LoRa Basics Modem，以及 LoRa Cloud™ 服务。

LoRa Edge LR1110 收发器是一种颠覆性的多技术地理定位解决方案，可帮助客户显著降低成本，并减少物联网资产追踪和监测解决方案的设计复杂性。收发器利用 GNSS 追踪室外应用和 Wi-Fi 无源扫描，从而追踪室内资产——在单个芯片上实现连续的室内-室外追踪。

The LoRa Basics Modem-E is a powerful new embedded software that provides the tools to connect and transmit device location data over the widely adopted LoRaWAN standard, and is certified by the LoRa Alliance® as LoRaWAN Certified^CM. The LoRa Basics Modem is a version of a modem operating on the LoRaWAN standard that is provided in source format. Both modems seamlessly integrate core modem functions with provisioning, geolocation and device management into device-side APIs that seamlessly interact with the Cloud-based solver and services. End devices no longer need powerful MCUs to host the modem stack. They can run the application on simplified MCUs.

LoRa Cloud 是 Semtech 开发的云服务产品，具备地理定位求解器、调制解调器管理服务以及使用了为 LoRa Edge 平台创建的 LoRaWAN 标准的连接服务器。地理定位求解器这一功能是为了与 LoRa Edge 器件配合工作，以处理 GNSS 和 Wi-Fi 扫描，发回器件的纬度和经度。

除了新的可用频率外，LoRa Edge 还增加了一些新功能，包括具有 FUOTA 补丁功能的最新固件、增强的 GNSS 精度（在 LoRa Basics Modem-E 和 LoRa Basics Modem 上具备多帧过滤功能，以及仅 LoRa Basics Modem 具备的多扫描求解功能），以及对 C 类多播下行链路的支持。

Next-generation Geolocation

通过消除对增量 GNSS 和 Wi-Fi 组件的需求，LoRa Edge 削减了器件的物料清单 (BOM) 成本，并显著降低了设计和采购的复杂性。LoRa Edge 加入了 LoRa Cloud Geolocation Services，可在云端提供易于使用且经济高效的基于 GNSS 和 Wi-Fi 的位置计算，以显著降低器件功率需求并提高资产管理效率。这样就更加方便客户管理总体拥有成本 (TCO)，并仅在需要定位资产时支付。

Enhanced position data gathering that offers the best balance between location accuracy and low power consumption is helping to transform multiple smart industries, including logistics, transportation, industrial, building, agriculture, healthcare, and more.
